- Growing global population and climate change threaten food security
- there is limited land to grow more groups
- C3 crops (e.g., rice, wheat, soybean) are limited by photorespiration, inefficient carbon fixation, and inefficient water use
- all made worse under climate change factors (heat and drought)
- Improving photosynthesis is a promising strategy for increasing crop yield and resilience
- Bioengineering photosynthesis is a frontier for sustainable agriculture
